Two laptop 2-core with 3gb and 4gb memory card and G210M GT520M game heats them very much, uses 40-50% of the CPU. I tried on a desktop Core2 Quad 9400 and the ATI HD6670 16gb game uses 20-25% (one core completely). It's just a travesty, I consume less, and Team Fortress Dungeon Defenders

There are ways to fix?
